Effects of structural steels microstructure and waveform on corrosion-fatigue behaviour of offshore wind turbine foundations.

Igwemezi, Victor Chinedu (2019-10)

Marine structures in the offshore environment are subjected to constant cyclic wave and wind forces. Also, the foundations are in direct contact with seawater (SW), hence introducing corrosion damage in the structure. Due ...
Experimental investigation of mechanical and fracture properties of offshore wind monopile weldments: SLIC interlaboratory test results

Mahmanparast, Ali; Taylor, Jessica; Brennan, Feargal Peter; Tavares, I. (Wiley, 2018-05-31)

S355 structural steel is commonly used in fabrication of offshore structures including offshore wind turbine monopiles. Knowledge of mechanical and fracture properties in S355 weldments and the level of scatter in these ...
Fatigue damage analysis of offshore wind turbine monopile weldments

Biswal, Romali; Mehmanparast, Ali (Elsevier, 2019-08-25)

Offshore wind turbines (OWT) are subjected to harsh environmental conditions in addition to the variable service loads. The present study is aimed at performing a realistic fatigue life estimation of the monopile structure ...
Fatigue life assessment of offshore wind support structures in the presence of corrosion pits

Shamir, Muhammad; Braithwaite, Jarryd; Mehmanparast, Ali (Elsevier, 2023-08-14)

Offshore wind turbine support structures, which connect the wind turbine transition piece and/or tower to the seabed, are located below the sea level and are in direct contact with seawater during the entire lifespan; ...
The influence of microstructure on the fatigue crack growth rate in marine steels in the Paris Region

Igwemezie, Victor C.; Mehmanparast, Ali; Brennan, Feargal (Wiley, 2020-07-28)

This paper presents a study on the effect of microstructure on the fatigue crack growth (FCG) rate in advanced S355 marine steels in the Paris Region of the da/dN versus ΔK log–log plot. The environments of study were air ...
Waveform and frequency effects on corrosion-fatigue crack growth behaviour in modern marine steels

Igwemezie, Victor C.; Mehmanparast, Ali (Elsevier, 2020-01-25)

The primary focus of this work is to investigate the sensitivity of cyclic waveform, frequency (f), load level and microstructure on the corrosion-fatigue crack growth rate (CFCGR) in modern normalised-rolled (NR) and ...
